Help me with compiling Nougat from the latest OSS sources

[t-shock]

Hi to everyone
I have been trying to make a Nougat OS out from the OSS sources but I have lots of issues
The main issue is that when it tries to repo init the source from the OnePlus, it says 404 not found. It works though with the Google sources just fine
Any help or ready build will be appriciated

PS The main reason that I want the OSS build is to prove that it is more optimized than the actual OOS
